Dave Grohl got to celebrate the Foo Fighters' 20th anniversary of their self-titled debut LP at a huge Fourth of July concert in his onetime hometown of Washington, D.C.

It was a show that many figured he and the band would have to miss after he broke a leg and dislocated an ankle falling off a stage in Sweden last month, but Grohl would not be deterred. "I would never have canceled this show. This is the one!" he told the crowd. Not only did he sport a purple cast, but he motored around the stage in a mobile throne with flashing lights, a display of guitar necks and the band's FF logo.

Grohl told the crowd that he conceived the design for the throne while he was high on morphine and oxycontin in the hospital during an introduction to "Big Me," the sixth song in a two-and-a-half-hour show. Later on, he dedicated "For All the Cows," from Foo Fighters' debut album -- which was released on July 4th, 1995 -- to his mother, Virginia Grohl, and brought her out on stage.

The show ended with two covers during a fireworks display -- Jimi Hendrix's version of "The Star-Spangled Banner" and AC/DC's "You Shook Me All Night Long."

The festival-style show, which offered performances by Joan Jett and others, also served as the kickoff of Foo Fighters' summer tour. The next show is on July 7 (Tuesday) in Camden, New Jersey.
